Abstract
A control is provided for louver blinds of the kind that hang vertically, although it would work for horizontally extended blinds and any other curtain or window cover in which both a double chain and a double cord or their equivalents were used. The control provides longitudinal channels through which the chains and cords pass, and are controlled by a cam and release bar arrangement to grip one of the cords, and three plungers to grip the other cord and two chains and exit the opposite side of the body of the control so that the control is easily gripped in one hand with the release bar pressed by the fingers and the thumb pressing a selected one of the buttons, or vice versa, so that all blind movements are made by pulling the control down, and lifting it back up in idling mode to pull down again, if necessary.
